Description
Integer overflow in base/ftstream.c in libXft (aka the X FreeType library) in FreeType before 2.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted Compact Font Format (CFF) font file that triggers a heap-based buffer overflow, related to an "input stream position error" issue, a different vulnerability than CVE-2010-1797.
